ABSTRACT

FIELD OF THE INVENTION

This invention pertains to a composition containing a hydrophobicallymodified polyacrylamide and a method of using the composition forconsumer and/or industrial applications.

BACKGROUND OF THE INVENTION

Surfactants have been widely formulated in cleansing products incosmetic applications. The major function of surfactants in rinse offproducts is to cleanse the skin and hair of fatty and water-solubleimpurities, however, surfactants meanwhile also cause irritation.

In skin care applications, surfactants function to remove normal skinlipids. The natural water-lipid film that functions to protect the skinis disturbed with every wash. Hydrophilic groups of the negativelycharged polar surfactant anions react with the weakly cationic,positively charged amino groups of proteins of the skin and mucosa.Therefore, surfactants are known for their irritancy to eyes anddefatting to skin, this is especially the case for anionic surfactants,which react with proteins in the skin and mucous membranes. The similardefatting effect from surfactant is also true in hair care. The mostcritically assessed surfactants are sodium lauryl and laureth sulfate,which can significantly cause hair harshness after the shampooing.

Another important aspect of surfactants is their foaming properties.Consumer's perception of foam is physiologically related to the efficacyof cleansing. The products that generate large volume and size of foamduring application are often perceived to have better a cleansingeffect. The typical surfactants of fatty alcohol sulfates generate goodamounts of foam with medium to large foam bubble sizes.

In both hair care and skin care applications, many polymericconditioners and emollients are inherently hydrophobic and they tend tobe difficult to be spread and can leave deposits left on skin or hair ifthe formulation has poor wetting properties. Therefore, wetting isanother important property to be assessed. Surface tension is used asone of the tools for the evaluation of wetting property. Commonsurfactants, e.g. fatty alcohol sulfates, have low surface tension,which helps to enhance the wetting attribute in formulations for hairand skin.

One major concern for surfactants is their irritancy. Many studies havebeen done over the decades to reduce the irritancy and defattingdisadvantages of surfactants. However, over the course of thedevelopment of low irritancy surfactants, scientists often have adilemma: in exchange for low irritancy the foam property was sacrificed.

An alternative surfactant to fatty alcohol sulfates is thereforedesired.

EXAMPLES Example 1 Modification of Acrylamide-Sodium Acrylate Copolymerwith Dodecylamine

To a Parr reactor is added an aqueous solution of acrylamide-sodiumacrylate copolymer solution (70:30 mole percent, 12 percent polymeractives, 291.7 g), a mixture of aqueous sodium hydroxide solution (50%,1.8 g) and aqueous sodium metabisulfite solution (15%, 14.9 g) anddeionized water (40.7 g). Finely ground dodecylamine is then added andthe mixture is thoroughly stirred. The reactor is then sealed, thestirring is set to the maximum setting and the reactor is pressurizedwith nitrogen and vented (repeat five times). The reactor is thensealed, heated to 140° C. and maintained at 140° C. for five hours. Themodified polymer solution is cooled to 90° C. at which time a mixture ofmethyl paraben (0.4 g), propyl paraben (0.1 g) and deionized water (20g) pre-heated to 90° C. is added to the hot polymer solution. Themixture is stirred for one hour and then cooled to ambient temperatureto provide the hydrophobically modified polymer or hydrophobicallymodified polyacrylamide solution.

Example 2 Foaming

The evaluation of foaming property of hydrophobically modifiedpolyacrylamide or hydrophobically modified polymeric surfactants wasdone using the Hart DeGeorge Test method. The method uses a blender togenerate the foam. The foam produced is thick and creamy and similar tothe foam in practical use of rinse off products. The shampoo solution isagitated in a blender for one minute. The foam is then poured into afunnel placed on a sieve with a #20 mesh screen. A gauging wire isplaced 80 mm from the bottom of the funnel. The time for the level offoam to reach the wire (seconds) is recorded; the higher the number, thebetter the foam.

Table 1 lists the shampoo base formulation used for the foam evaluation.Polymeric surfactant or benchmark was added in the ingredient called“polymer” at 0.5% or 1.0% actives.

The foaming evaluation is summarized in Table 2.

TABLE 1 Shampoo Base INCI (International Nomenclature for Ingredient Wt.% Ingredient in Cosmetic Ingedients) Concentration % Formula Water 35.0 Sodium lauryl sulfate 30 20.0  Sodium lauryl ether 30 20.0  sulfateCocamidopropyl betaine 30 3.0 Lauramide DEA 100 3.0 Citric acid 100 0.3Sodium Chloride 100 1.0 Polymer 0.5 or 1.0 (active) Disodium EDTA 1000.1 DMDM Hydantoin 55 0.1 Water Qs pH adjustment 50

It is clear that Nalco's polymeric surfactant (5605-192) almost doubledfoam performance compared to the control.

Example 2 Surface Tension/Wetting Properties

Surface tension, a tool to evaluate wetting properties, was alsomeasured. A mixture solution of polymeric surfactant and commonsurfactants was prepared at a 3/17 ratio in an active base and dilutedwith water to 0.6%. The surface tension was tested on a surface tensioninstrument (Kruss Processor Tensiometer K-12) and average from 5replicates was reported in table 3. Table 3 shows the test result.

TABLE 3 Surface Tension Measurement Surface Tension Sample Name (mN/cm)Standard Deviation Water 72.05 0.00994 SLES/Cocamidopropyl 30.94 0.01091betaine SLES/Nalco polymeric 32.42 0.09029 Surfactant (5605-192)

It is clear that polymeric surfactant (5605-192) has comparable surfacetension to the benchmark (cocoamidopropyl betaine) which is usedcommonly to boost foam.
